CONSTRUCTION FIELD TOOLS
A field book that does the math.
Record a grade check, estimate a trench quantity, and keep the inputs with a clear job report. Driftless Field brings those tasks into one small workspace.
From measured ground to a road section.
Set left and right road widths, crown/crossfall and optional side slopes. Each side ties to measured ground; cut and fill remain separate. Preview a chart, save stations, and estimate volumes by average end area with a separately stated allowance.
Pro chart sheets support Letter, Tabloid, A4 and A3 landscape, explicit horizontal scale, vertical exaggeration, black-and-white output and your uploaded or photographed company logo. Print at actual size and verify the one-inch reference bar.
Your record travels with the result.
Each saved observation keeps the benchmark, backsight, foresight, target and tolerance. Export CSV for a spreadsheet, print a field report, or download a job backup to move to another device.
Simple by design
- No AI call is needed to calculate a result.
- Your job contents stay in this browser.
- Reports show the assumptions used.
- Example jobs are labeled synthetic and kept separate from your work.
Free and Pro
The four calculators are free and stay free, and so is one saved job with its backup download. Pro adds unlimited saved jobs, saved cross sections, scaled chart sheets, company logos, printed field reports and CSV export. A Pro licence key is checked on your own device — there is no account to create and nothing is uploaded.
